18 Claims.

This invention relates to cooking ranges particularly adapted for installation within confined spaces such as automobile trailers, boat galleys, small cabins, and like compartments where space is limited. For example, in automobile trailers the space allotted for a cooking range is usually over the wheel housings and is so limited and closely confined that it is impossible to install conventional cooking ranges having sufflciently large oven and cooking top to provide the necessary baking and cooking capacities, especially without producing fire hazards and an inconvenient working level of the cooking top. These difficulties are further aggravated for the reason that ranges of this character should be light in weight, of rigid construction, safe in operation, and preferably contain their own fuel supply and generating system.

It is, therefore, the principal objects of the present invention to provide a cooking range having the required cooking and baking capacities and which may be conveniently and safely installed in limited and closely confined space; to provide a strong, light weight sheet metal construction in which the usual frame structure is eliminated; to provide for circulation of air beneath and at the back of the range in cooperation with insulation to eliminate fire hazards and promote efliciency of operation; to provide a burner cover for the cooking top; and to provide a construction which assures positive circulation through .the oven and ventilation from the top of the stove.

Another object of the invention is to provide a relatively inexpensive range construction that is readily assembled with minimum fastening devices which are not affected by vibration.

In accomplishing these and other objects of the invention, as hereinafter pointed out, I have provided improved details of structure, the preferred form of which is illustrated in the accompanying drawings, wherein:

Fig. 1 is a perspective view of a cooking range constructed in accordance with the present invention, the burner cover being shown in open position and the grates removed to better illustrate the top of the range structure.

Fig. 2 is a horizontal section through the range, particularly illustrating the sheet metal construction thereof.

Fig. 3 is a vertical section through the range on the line 33 of Fig. 2.

Fig. 4 is a section through the range taken at right angles to the section shown in Fig. 3.

Fig. 5 is a section similar to Fig. 3, but taken in disassembled spaced relation.

Referring more in detail to the drawings:

I designates a range constructed in accordance with the present invention and which is especially designed for use in restricted spaces as above noted, and which includes a sheet metal casing 2 of substantially rectangular form and of a'size to fit within an allotted space. The entire front 3 and sides 4 and 5 of the casing preferably consist of a single sheet of metaL'bent on slightly rounding curves to form the front vertical corners 6 and l of the casting, the terminal edges of the sheet being flanged inwardly, as at 3 and 9, to form the rear vertical corners and attach a back sheet Ill, later described.

The upper and lower edges of the sheet are also flanged inwardly, as indicated at H and i2, the flanges being notched, as at l3 and H, to permit of the bends forming the corners 6 and I. The front 3 is provided with substantially rectangular shaped door openings l5 andl6having the marginal edges thereof flanged inwardly as at i'|-l8, i920, 2l-22, 2324 respectively, to frame the openings and cooperate with the flanges ii and I! in stiffening the front 3 and provide for attachment of interior structure.

- The front 3 is also provided below the openings with louvers 25 partially covering slotted air inlet openings 26 and the portions thereof above the door openings are provided with preferably I horizontally aligned apertures 21, 28', 29 and 30 to pass the valve stems of the burner control valves later described. The upper edge of the opening it is notched through as at 3| to pass thegenerator unit 32 supplying fuel to the respective burners.

The door opening 15 provides access to the oven of the range and is therefore wider than the opening l6 which is only sufficiently wide to accommodate the fuel supply unit, as later described.

Fixed to the inturned flanges l2, preferably by welding, is a bottom sheet 33 covering the bottom of the range and having an upwardly flanged rear edge 34 cooperating with the flanges 8 and 9 to attach the back sheet Ill. With the bottom sheet 33 secured to the inturned flanges of the front and sides 4 and 5, it retains the rectangular shape of the lower portion of the range. Fixed to the inturned flanges l1 and I8, at the sides of the opening ii, are partition or oven side sheets 35 and 36 which extend parallel with the sides 4 and 5 in spaced relation therewith, and terminate in plane with the inner faces of the flanges 6 and 9 in lateral flanges 31 and 36, the flange 31 abutting against the inner face of the flange 9, as clearly shown in Fig. 2.

Likewise attached to the side flanges 2| and 22 of the opening I6 are partition sheets 39 and 46, the partition sheet 39 having a laterally turned flange 4| along its rear edge overlapping the flange 38 of the partition sheet 36. The sheet 46 extends in spaced parallel relation with the side 4 across the major portion of its width to provide an insulating and air circulating space 42 for the outer side of the tank compartment. The rear portion of the sheet, however, is offset in the direction of the side 4 as indicated at 43 to give additional room for an oven burner supply pipe 44, later described, and the terminal edge has a lateral flange 45 abutting against the inner face of the flange 6. The partition sheets just described also have lateral flanges 46, 41, 46 and 49 respectively extending along the lower edges thereof to engage the bottom sheet 33, the flanges 46 and 49 overlapping the inturned bottom flanges I2 of the sides 4 and 5 and the flanges 41 and 46 overlapping each other as clearly shown in Fig. 4.

The partition sheets 35, 36 and 39 extend in height to the upper edges of the openings I5 and I6, and they are also provided with lateral flanges 56, 5I and 52, with the flanges 5I and 52 overlapping as shown in Fig. 4. The sheet 46, however, extends the full height of the range and terminates in a lateral flange 53 engaging under the upper inturned flange II of the side 4. Inset between the sheets 35 and 36 is a pan-like lining sheet 54 having flanged sides 5556 and a flanged front 51 which terminate in lateral flanges 58, 59 and 66 respectively, the flanges 56 and 59 resting upon the flanges 56 and 52, and the flange 66 upon the upper inturned flange I9 at the door opening I5. The rear edge of the sheet 54 terminates in a downwardly extending flange 6| which abuts the back oven liner sheet 62, which cooperates with the back sheet I6 in forming an insulating compartment 63.

The front edges of the sheets 35, 36, 39 and 46 may be secured to the flanges at the sides of the door openings in any suitable manner, but are here shown as being secured by fastening devices, such as bolts 64, having shanks extending through openings 65 in the flanges, through registering openings 66 in the partition sheets, and into threaded nuts 61 which are preferably secured to the partition sheets so that the fastening devices may be readily threaded thereinto. The fastening devices which secure the partition sheets 38 and 39 also constitute supports for attachment of door hinges 69 and 16 of doors II and 12 that close the respective openings, as shown in Fig. 1, the door I2 being secured by a spring latch I3 engageable over a head of one of the fastening devices attaching the front edge of the sheet 46. The other or oven door II is retained by a tongue I4 flxed on the inner end of a shaft I5 rotatably mounted in a door structure and operable by a handle I6 to engage in a slot 'II formed in the partition sheet 35, as best shown in Fig. 2. The doors II and I2 are also formed of sheet metal and have inwardly flanged marginal edges I6 arranged to overlap the side edges of the door openings. The oven door includes a body sheet I9 and a liner sheet 86 having offset marginal edges 6| welded to the body sheet to form a space for containing an insulating material 62. The hinges 69 are attached to the body sheet and the assembly is retained in the outer or finish sheet by tongues 63 that are attached to the outer or flnish sheet and bent over the flanges of the liner sheet.

Inset within the top of the range, and resting upon the flanges 5659 of the sheet 54 and on an inturned leg 64 of an angle 65 that is attached to the partition sheet 46, is a horizontal, sheet-like partition member 66 constituting the bottom of a burner chamber. The front edge of the sheet 66 overlies the flange 66 and the rear edge extends to the plane of the back sheet and has an upwardly directed flange 61 abutting thereagainst. When this sheet is secured in position it cooperates with the bottom sheet in maintaining the cross-sectional shape of the range. This member also cooperates with the sheet 54 to provide an air space or passage 66 extending over the top of the oven, which space is connected with the oven chamber through a plurality of spaced vent apertures 69 that are formed in the front portion of the sheet 54. This space has an exhaust through a slot-like opening 96 at the rear edge of the horizontal partition member 66 to provide ventilation from the top of the oven into the burner chamber 9| which constitutes the space between the horizontal partition member 66 and grates 92.

The grates 92 constitute the cooking top of the range and have their outer side and front edges supported upon the inturned flanges II, while their rear edges are supported on a depending flange 93 extending along the inner edge of a tie bar 64 to which a burner cover 65 is secured by hinge elements 96. The grates are retained in position by suitable fastening devices which are readily manipulated to permit removal thereof when it is desired to have access to the burner chamber. When the top cover is closed, the burner chamber is vented through a slot-like opening 91 in the bar 94.

Fixed within the oven chamber to the inner faces of the partition sheets 35 and 36 are substantially channel-shaped members 96-99 and I66--I6I, arranged with the flanges I62 thereof turned inwardly to constitute guide tracks for oven racks I63 and an oven bottom sheet I64, the oven bottom sheet I64 being supported on the lower flanges in substantial registry with the inturned flange 2| at the lower edge of the door opening. The oven bottom sheet I 64 has the marginal edges flanged downwardly as at I65 to enhance the rigidity thereof and the side portions are provided with a series of vent openings I66 and I6! whereby air is admitted to the oven from the oven burner chamber by way of the louver openings 26. The oven bottom sheet I64 also carries an insulating material I66 that is retained by a plate I69 located directly over the oven burner H6 and secured in position by suitable fastening devices I I I.

The racks I63 are of wire-like construction and have side bars II2 resting on the guide flanges and front and rear bars I I3 and H4 carrying rods II5 therebetween. Fixed to the d II5 adjacent the rear bar II4 of the racks is a cross bar II6 having oflset ends III and H6 engaging under the respective guides I62 to retain the respective racks for sliding support to and from the oven. The offset ends Ill and H8 are admitted to the under sides of the guides I62 through gaps II9 and'l26 that are formed therein, as best shown in Figs. 1, 2 and 6.- Steps I2I are provided at the under sides of the guides at their forward ends in the form of angleshaped braces I22, the rear ends of which are adapted to be engaged by the offset ends Ill and III to limit withdrawal of the racks.

The oven burner H is carried on a box-like support I24 of rectangular shape but is smaller in dimension than the oven. The front and rear sides of the support are provided with flanges I25 and I26, the flange I25 of which terminates in a foot I21 fixed to the bottom sheet 33. Fixed to the flange I25 is a vertical plate I23 which has a foot I23 similar to the foot on the flange I26 and carries the front of the-oven burner. It also serves as a heat baifle for protecting the front flnish of the stove. The side edges of the support I24 are flanged downwardly as at I30 to enhance the rigidity thereof and provide an air passageway thereunder for flow of air admitted through openings I3I (Fig. 6) in the bottom sh'eet into the oven.

Extending across the bottom of the range, and attached to the lower face of the bottom sheet 33, are spaced channels I32 and I33 having downwardly directed flanges I34 constituting feet for spacingly supporting the bottom of the range from direct engagement with the base on which the range may be mounted, and thereby providing passage of air necessary in supplying the oven and the burner chambers through the openings I3I and 26, the attachment points of the channels being reinforced by angles I32 extending across the inner face of the bottom sheet and which cooperate with the channels to clamp the bottom sheet therebetween as best shown in Fig. 4. Y

Extending across the space between the par tition sheets 33 and 40, at a point spaced below the inwardly directed flange at the upper edge of the opening I5, is a sheet I35 cooperating with the upper portions of the sheets 33 and 40 to form a tank carrying compartment which is insulated from the burner chamber of the cooking top by the horizontal partition member 36 extending thereover. The sides of the sheet I35 have flanges I36 adjustably attached to the partition sheets by fastening devices I31 extending through slots I33 in the flanges I36 whereby the tank unit I carried therein is adjustably supported to bring the generator of the tank unit into alignment with the Bunsen or burner inlet. The rear edge of the support is spaced from the back sheet to provide an air passageway therebetween. Fixed to the upper face of the support are guide rails I33 and I40 for more accurately guiding the fuel tank I into position in the range.

It is thus obvious that the tank unit is supported within the casing with its attached generator properly aligned with the burner inlet and is removable therefrom as a unit for fllling purposes similarly to the tank units disclosed in United States Letters Patents Nos. 1,637,554; 1,716,210; 1,716,213, and 2,128,171.

The burners in the burner compartment, as well as the oven burner and its connection with the generating system of the range, are covered.

in a separate application and specifically form no part of the present invention. However, they are briefly described in that the arrangement thereof forms a part in providing the desired cooking capacity of the range.

' The burners for the cooking top are illustrated as three in number, and are supported by suitable brackets I42 and I43 carried in a pan I44, the pan I44 being mounted upon the horizontal partition member 36 and provided with sides I45 to retain any liquids that may be spilled from the cooking utensils. The pan is attached to the member 36 at points over the flanges of the partition sheets 36 and 33 by fastening devices I46 which extend through upwardly struck bosses I4lof the pan I44. The

end of the pan which extends over the tank compartment acts as an additional insulating member associated with the casing for insulating the tank from the burner units.

The burners are supplied from a common manifold I48 connected with a common mixing chamber I43 located in position to receive the generating tube 32 that is carried by the fuel tank I and in operative position aids in supporting the tank unit in aligned position with the burner inlet. The manifold I43 connects with the pipe 44 which extends downwardly within the fuel tank compartment and terminates in an .elbow I50 having connection with the burner IIO by a pipe I5I extending through suitable openings in the partition sheets 36 and 33. The burner manifold is further anchored within the burner chamber by means of a lug I52 that extends rearwardly therefrom and is secured to the rear sheet I0 by a fastening device I53.

The generating tube is connected with the tank by a collar-like fltting I54, having sliding engagement in a slot I55 of the partition member 36, which registers with the notch in the front wall so that when the tank is slid along its main supporting member, the collar will pass into the slot and center the generating tube with respect to the mixing chamber.

The burner assembly also includes a sub-flame burner I56 that is located below the generating tube. The fuel tank is locked in operative position by means of an adjustable hook-like stop I51 engaging the rear end of the tank and an adjustable, spring-pressed latch I53 engaging the front end of the tank to properly locate thetank and generating tube as best shown in Fig. 5. The burner manifold may be provided with a sump I53 whereby excess liquid may be drained from the range through a pipe connection I50. In order to space the oven from a wall against which it may be placed, the back sheet I0 preferably has its ends flanged outwardly as at I6I and I62 to assure an air passageway therebetween. These flanges also reinforce the sheet and assure tight joints at the edges thereof.

In assembling the range, the bottom sheet 33 including th burner support I24 attached thereto is welded to the lower inturned flanges I2 of the front 3 and side walls 4 and 5. The partition sheets 35, 36, 33 and 40 are then inserted between the side walls and secured to the flanges Il, I3, 2I and 22 at the sides of the door openings I5 and I6. The lining sheet 54 forming the top of the oven is then slid into position so that the flanges 53 and 53 thereof are supported on the flanges 50 and 5| of the partition sheets 35 and 36 which form the sides of the oven. The inset partition member 36 may then be applied and secured in position by fastening devices extending through the respective overlapping flanges of the lining sheet and the partition.

sheets 35, 36 and 40, and the flange 34 of the angle 35, so that the horizontal partition member cooperates with the bottom in maintaining the rectangular shape of the casing. The sheet I35 forming the bottom of the tank compartment is inserted between the walls 33 and 40 and secured by the fastening devices I31 after the ad- Justment as to height has been made. The tie bar 94 is applied to the upper flanges of the side walls. The upper burner unit carrying the pipe and fitting I50 are assembled on the pan I44 and the assembled unit is inserted into the burner chamber of the cooking top through the open back of the casing, after which the oven burner H is connected with the upper burner unit by inserting the pipe ll. Suitable insulation may be inserted in the Spaces between the side wall 5 and partition sheet 35, and the partition sheets 36 and 39 respectively. The oven back liner sheet 62 is then inserted between the partition sheets 35 and 36 so that it comes into abutting engagement with the ends of the guidetracks, after which a sheet of insulating material is superposed thereagainst and the back sheet In is attached by fastening devices extending through openings therein, through registering'openings in the flanges and into threaded nuts secured to the flanges, after which the. grids are secured in posichamber and the top of said fuel tank chamber.

tion on the upper flanges H and the burner cover 95 may then be applied to the tie bar, completing the assembly. Adjustment of the sheet i35, stop l5! and latch E58 may be necessary to properly locate the tip of the generator tube with its Bunsen. This, however, is easily effected by the slotted connections as shown in Fig.5.

From the foregoing it is obvious that I have provided a range construction wherein the casing is completely formed of sheet metal, the parts of which, when connected, provide an extremely rigid construction without the use of interior frames, bracing, and the like, thereby providing a light weight, rigid construction. Elimination of frames, bracing and the like also provides for larger oven space and provides a cooking top which includes the entire top of the casing. It is also obvious that I have provided for adequate ventilation through the oven and provided for circulation of air under and at the back of the range so as to avoid heating of the base or walls against which the range may be placed.
